What does the Bible say about who are God's people?

The Scriptures reveal that being part of God's people transcends biological lineage or ethnic identity. In 2 Corinthians 11, Paul emphasizes that not all who share the lineage of Abraham are God's people. Jesus echoes this in John 8:39, stating that true descendants of Abraham will display the works of faith, indicating that mere DNA does not define God's chosen ones. Rather, it is those who are spiritually reborn in Christ who are considered to be His people, as seen in Galatians 3:28, where Paul asserts that all who belong to Christ are Abraham's seed.
